A fuel or brake line drops out of a clip under gas tank. This is not an isolated situation. I've seen this line dragging about 4" above the highway on other Crown Victoria's and Mercury Grand Marquis that I pass on my way to and from work. It could rupture if the undercarriage makes contact with the pavement, such as elevated driveways, parking lot entrances, or pot holes. It could also be torn by road debris. My neighbor put my line back in the clip for me. He thought it was probably a fuel line, but he was not sure. If it is a fuel line and it ruptures when the undercarriage makes contact with the pavement, a spark could it ignite the gasoline causing a life threatening situation. If it is a brake line, it could be potentially life threatening if it becomes ruptured or torn. Whatever type of line it is, the problem could easily be rectified by replacing the clip with one that would not permit the line to become dislodged during normal driving. My car has never been off the road. All my driving has been highway or city driving and somehow the line became dislodged.

The fuel line is exposed under the rear of the vehicle and sometimes drags the ground.
